Abstract

The indoor air quality is related to the comfort and health of the people inside. The causes of poor air quality or stuffiness can be influenced by three parameters: temperature, humidity, and the levels of carbon dioxide. To detect air quality, an IoT-based system was developed to monitor the status of indoor air quality. The air quality statuses defined in this study include not stuffy, moderately stuffy, stuffy, or very stuffy. The sensors used in this study are DHT11 and MH-Z19B. Testing was conducted in three different rooms: Computer Laboratory A, Computer Laboratory B, and the Workshop Laboratory of the Computer System Engineering program at Tanjungpura University, Pontianak. The results of this study include a device that displays information on temperature, humidity, and carbon dioxide levels on a 16x2 LCD with LED lights that turn on when parameter values exceed the set thresholds, and a website. The average detected temperature was 27.51°C, humidity was 52.34%, and the average carbon dioxide level was 703.36 PPM. Based on these three parameters, the average detected air quality status was moderately stuffy. The system was able to detect indoor air quality with an overall average system accuracy of 90.31%.

Abstract

Infusions are clinical equipment for administering liquid medication or nutrients to patients. Infusion fluid is stored in a sterile bag and delivered to a vein through a tube. Infusion monitoring is usually done manually by nurses, which often results in negligence such as replacing the liquid run out too late, handling infusions that are not dripping, and dealing with blood that rises into the infusion hose. Therefore, a real-time monitoring system is needed that can provide information and remote notifications about the condition of the infusion. This research develops an IoT-based system using NodeMCU ESP32, Loadcell sensor, TCRT5000 sensor, LDR sensor, Node-RED, and Telegram bot application. NodeMCU ESP32 serves as the main controller. Loadcell sensor gauges volume of the infusion fluid, TCRT5000 sensor counts droplets per minute, and LDR sensor detects blood in the infusion hose. Sensor data is sent to Node-RED for processing and display on the Telegram bot application. The accuracy of the Loadcell sensor reaches 95.69%, while the TCRT5000 sensor has an accuracy of 76.73%. Notifications are sent when the infusion fluid volume is less than 100 ml, the infusion fluid is not dripping, and when the LDR sensor detects blood in the infusion hose.

Abstract

This study addresses the issue of air pollution in Pontianak, marked by high levels of pollutant particles and chemical compounds that cause respiratory health risks. The research involves essential air quality monitoring using various sensors for temperature, humidity (DHT22), O2 (MQ-135), CO (MQ-7), CO2 (MG-811), and dust (GP2Y1010AU0F), collected real-time, leading to a notable increase in data volume. Due to limitations in internet of things (IoT) devices, there is a need for integration between cloud and IoT through data transmission to reduce the communication time and memory usage. The escalation in sensor data volume requires a lossless compression technique to ensure efficient storage without sacrificing crucial information. Compression plays a vital role in overcoming complex storage challenges, facilitating real-time data access for monitoring, and contributing to sustainable efforts to improve air quality in Pontianak. This research applies the D-RAKE compression method based on basic counting procedures with minimal memory requirements, cost-effective, low-speed microcontrollers commonly used in IoT devices. Despite its simplicity, simulation results indicate that the D-RAKE algorithm outperforms well-established compression methods such as gzip, bzip2, and rar, particularly for data sequences with sparse elements. Moreover, when applied to real- world data, D-RAKE achieves superior compression ratios compared to IoT-focused compression techniques.

Abstract

Pengendalian efisien perangkat listrik, terutama lampu, memegang peran krusial dalam manajemen energi listrik. Salah satu permasalahan yang umum dihadapi adalah kelalaian pengguna dalam mematikan lampu saat siang hari, mengakibatkan pemborosan energi. Untuk mengatasi isu ini, penelitian ini mengusulkan solusi inovatif berupa sistem otomatisasi lampu berdasarkan kebiasaan pengguna,  khususnya  menggunakan metode klasifikasi K-Nearest Neighbor (KNN). Metode KNN digunakan untuk memahami pola perilaku pengguna dalam menghidupkan dan mematikan lampu pada waktu tertentu. Penelitian melibatkan 620 data latih dan 72 data uji. Hasil uji variasi nilai k menunjukkan bahwa semakin besar nilai k, tingkat akurasi cenderung menurun. Dalam penelitian ini,  berdasarkan  pengujian dengan  confusion matrix penerapan metode KNN dengan nilai k sebesar 3 menghasilkan tingkat akurasi mencapai 99,76%, recall 100%, dan presisi 99,48%. Penelitian  ini menunjukkan bahwa pendekatan ini mampu secara efektif memahami kebiasaan pengguna dalam mengoperasikan lampu, sehingga sistem otomatisasi dapat memberikan respons yang tepat. Implementasi solusi ini dapat berpotensi mengurangi konsumsi energi secara signifikan dan meningkatkan kesadaran pengguna terhadap penggunaan listrik, mendukung upaya konservasi energi yang lebih luas.

Abstract

Sepatu sangat diperlukan dalam berbagai aktivitas seperti pergi ke sekolah, kampus, dan kantor. Sepatu yang sering digunakan perlu dicuci dan harus segera dikeringkan. Sepatu yang dibiarkan basah tanpa dikeringkan akan menyebabkan bau yang tidak sedap dan menjadi tempat berkumpulnya bakteri. Proses pengeringan sepatu umumnya dijemur di bawah sinar matahari, namun cara tersebut membutuhkan waktu yang cukup lama. Ketika cuaca cerah, terjadi hujan yang membuat proses pengeringan sepatu dengan memanfaatkan panas dari sinar matahari menjadi tidak efektif. Untuk solusi permasalahan ini, maka dikembangkan sistem pemantauan dan pengeringan sepatu otomatis berbasis IoT. Sistem ini mendeteksi kelembaban pada sepatu yang basah, agar dapat mengeringkan sepatu. Sistem ini mengirimkan notifikasi secara realtime ke chat bot telegram yang sudah ada di dalam grup Telegram, agar bisa memantau kondisi pengeringan sepatu kapanpun dan dimanapun. Sistem ini dapat mengirimkan notifikasi ke beberapa perangkat yang bisa digunakan oleh seluruh anggota grup Telegram. Hasil pengujian menunjukkan bahwa rata-rata waktu pengeringan sepatu pantofel 1 jam 5 menit 48 detik, rata-rata waktu pengeringan sepatu sneakers 1 jam 21 menit 48 detik, dan rata-rata waktu pengeringan sepatu olahraga 1 jam 30 menit 36 detik.  Kata kunci : Sepatu, IoT, Notifikasi, Telegram

Abstract

Catfish farming is one of the fisheries businesses that requires intensive attention to various environmental factors such as water quality, weather conditions, and feeding schedules so that productivity remains optimal. These conditions if not managed properly can cause a decrease in water quality which results in fish death or growth that is not maximized. To overcome these problems, an automatic control system based on the Internet of Things (IoT) was developed by utilizing the Arduino Uno microcontroller and ESP32 as the main components in the system. The system is equipped with various sensors, such as a pH sensor to monitor water acidity, an ultrasonic sensor to measure water depth, and a rain sensor to detect weather changes. In addition, the system is also equipped with relays, water pumps, and servos that function to regulate water conditions, automatic feeding, and automatic roof operations on fish ponds. This research was tested 72 times with different values of pH and ultrasonic sensor accuracy. The test results show that this system works without errors, with the pH sensor accuracy level reaching 89% and the ultrasonic sensor at 97%. With this automation system, it is hoped that catfish farmers can manage ponds more efficiently, monitor pond conditions in real-time, and increase cultivation productivity through the management of fish ponds.
